This invention relates to machines for removing stockings from forms such as that shown in United States Letters Patent llo. 1,126,619, dated January 16, 1915, wherein a stocking or a forin is placed between pairs of cooperating jaws arranged to grip the heel and foot portions respectively of the stocking and to hold such portions substantially stationary while the form is withdrawn from the stocking.

rllhe object of the present invention is to correct certain faults that have been found in machines evolved from the original inachine shown in the above noted Letters Fatent, and which will be fully disclosed hereinafter, reference being had to the accompanying drawings, of which:

Fig. 1 is a plan view of sufiicient of the machine to illustrate the application of the present invention thereto; u

Fig. 6 is a sectional elevation taken on the line @-6, Fig. 5;

F 7 is a sectional plan view taken on the line 7-7, Fig. 6;

Fig. 8 is a view similar to Fig. 5, but showing certain of the elements in a position to prevent closing of the gripping jaws; and

TEig. 9 is a sectional plan view taken on the line 9-9, Fig. 8. Y

In the machine shown in the present instance, a stocking forni with a stocking thereon is adapted to be placed between a pair of cooperating jaws 1 and 2 arranged to grip the foot portion of the stocking, and a pair of cooperating jaws 3 and l arranged to grip the heel portion of the stocking.

r1`hese grippers 1-2 and 3-4 are pivotalmounted on a non-rotating support-ing rod rlhe jaws 1-2 and 3-4 are connected by links, 6, 6 and 7, 7 to actuating levers 8, 8, secured to an actuating shaft 9.

The supporting rod 5 and the actuating shaft 9 carried in a suitable support 10 and project laterally therefrom as shown in Figs. 1 and 2. The supporting rod 5 is held against rotation while the shaft 9 is adapted to be rocked about its own aXis in the support 10 for opening and closing the gripping jaws as will be fully disclosed hereinafter.

The support 19 is arranged to be swung about a vertical axis, to assist in the removal of the forin froin the stocking and for this purpose is 'arovided with a hub 11 rotatably mounted on the lower end of a boss 12 formed on the outer end of an arm 113 which in turn is adapted to be swung about a vertical axis coincident with the axis of the vertical shaft 14 shown in Fig. 1, to assist in the reinoval of the stocking from the form.

The swinging of the support 10 and its c' frying arin 113 is accomplished by mechansin forming no part of the present invention, and for the purpose of simplicity is not shown in the present case.

The end of the actuating shaft 9, adjacent tue support 10, is provided with a lever 13 pivotal ly connected at its outer end by a link 16 to the lower end of an actuating rod 17.

rlie rod 17 is provided with a head 17 a on rests the lower end of a sleeve 19, the upper end of which is provided with a spiral cam surface 20. The cam surface 2O coacts with a similar cani surface 21 formed on the lower end of a collar 22 which is rotatably mounted on the uriner end of the rod 17 beitween the cani surface of the sleeve 19 and a fixed abutment-18 on the extreme upper end of the rod 17.

When tbe collar 22 is in the position shown in 5, 6 and 7. its upper end bears against the under-side of the fixed abutment k18 on the upper end of the rod 17, and holds the head 17a of lhe rod in firm contact with the lower end of the sleeve 19, in ordei that the sleeve 19, the rod 17 and the collar 22 will slide vertically as a unit within the boss 12.

Vertical movement upwardly of the rod 17, through the link 16, arm 13 and shaft 9,

closes the gripping jaws 1 2 and 3 4 and vertical movement of the rod 17, etc. in a reverse direction, downwardly, opens the said jaws.

The vertical movement of the sleeve 19 and the elements 17 and 22 as a unit is accomplished by a gear segment 23, the teeth of which meshes with rack teeth 24 formed, in the present instance, directly on one side of the sleeve 19.

The segment 23 is secured to one end of a horizontal shaft 27, on'the opposite end of which is a spiral gear 25. The gear 25 meshes 'ith a similar gear 26 secured to the upper end of the vertical shaft 14. This shaft is adapted to be rotated in one direction at a predetermined time to raise the sleeve 19 to close the jaws 1 2 and 3 4 for gripping a stocking and the form thereon; and at another predetermined time to be rotated in an opposite direction to lower the sleeve 19 to open the jaws 1 2 and to release the stocking after the form has been withdrawn therefrom. Rotation of the shaft 14 is accomplished by mechanism forming no part of the present invention and has not been shown.

The shaft 14 operates continuously and in timed relation to the conveying mechanism shown in the above mentioned patent and when forms emerge from the drier on which noy stockings have been placed, it is desirable that such empty forms do not contact with the grippcrs 1 2 and 3 4 and for this pur` pose the jaws 1 2 and 3 4 are maintained in an open position while the other elements function in a normal manner in timed relation to the elements of the drier.

To prevent the jaws 1 2 and 3 4 from closing, the collar 22 is turned about the aXis of the rod 17 during which the cam face 21 of said collar slides downwardly on the cam surface 2O on the upper end of the sleeve 19, from the position shown in Figs. 5 and G to the positions shown in Figs. 2 and 8, the rod 17 and the fixed abutment 18 on the upper end of the rod 17 at the same time moving downwardly from the position shown in Fig. 2 to the position shown in Fig. 8, the shaft 9 being thereb)7 turned in a direction to open the jaws 1 2 and 3 4 if and when the sleeve 19 is moving' or has moved upwardly in a normal j avv-closing operation.

It will be noted that in Figs. 1, 2, 5 and 8 of the drawings, the shaft 27 has been turned to raise the sleeve 19 to its highest jaw closing position, and by reason of the said turning of the collar 22 the rod 17 has been lowered from the position shown in Figs. 2 and 5 to the position shown in F ig. 8, whereby the jaws 1 2 and 3 4 have been moved from their closed positions in Figs. 2 and 3 to their open positions of Fig. 4, consequently when the sleeve 19 is lowered by reverse movement of the shaft 27 the sleeve 19 will merely slide Leleslo idly down the rod 17 which remains stationary with the jaws in the open position, leaving the iixed abutment 18 spaced well above the upper end of the collar 22, so that when thesleeve 19 is again raised it slides upwardly and idly on the rod 17 without affecting the quiescent position of the rod 17 and the jaws 1 2 and 3 4.

Turning of the collar 22 in an opposite direction, whereby the cam face 21 thereof slides on the cam face 20 on the upper end of the sleeve 19, again brings the sleeve 19 and collar 2 2 into full extended relation to each other, filling the space between the lower side of the fixed abutment 18 and the upper side of the head 17a ofthe rod 17, thus the rod 17, the sleeve 19 and the collar 22 will again operate as a unit.

' Difficulty has been encountered in maintaining the collar 22 in its fully extended position when the unit, of which the collar is a part, is operating normally as above described for periodically opening and closing the aws. The vibration of the machine tends to cause the collar 22 to rotate slightly about the rod 17 the cam surface 21 of the collar sliding down the cam surface of the sleeve 19 so that the aws 1 2 and do not close tightly upon a stocking inserted therebetween, thus the jaws lose their grip and do not remove the stocking from the form.

One object of the present invention is to preventthe above noted accidental improper closing of the a-ws and this object is attained by providing the collar, in the present instance, with a securing latch which will positively hold the sleeve against rotation when in its fully extending position with respect to the sleeve 19.

Referring to Figs. 5, 6 and 7, the collar 22 is provided with an operating handle 30 which is straddlcd, in the present instance by a spring-pressed latch lever 31, pivoted at 32 and provided above the handle with a thumb pad 33 and below the handle with a projection 34 which, extends into a relatively close fitting aperture 35 formed in the upper end of the sleeve 19, so that when the collar 22 is rotated to extend the collar as above noted, the said collar will be prevented from rotating in a manner to permit the collar cam surface to slide down the cam surface of the sleeve 19 and thus effect improper closing of the jaws 1 2 and 3 4. A spring 131 tends to force the projection 34 into its receiving cavity 35 at all times.

The coacting cam surfaces 20 and 21 serve another purpose, aside froinmerely extending the collar 22 above the sleeve 19, i. e. theseV cam surfaces provide for a relatively fine adjustment of the elements for regulating the pressure exerted upon the stocking by the jaws 1 2 and 3 -4, slight rotation of the collar minutely controlling the pressure exerted by the jaws on the stocking. lVith the the rod 17. 1n order to provide a positive adjustment between the rod 17 andthe sleeve 19 to regulate the pressure oi' the jaws on the stocking, to regulate the closing otl the jaws properly for stockings oit diiierent weights, and to provide for dihferent thickness in the forms on which the stockings are placed, the nut 18 is positively secured to the rod 17, as tor example by a pin 26, and the upper end ot the collar 22 is provided with a cup-shaped cavity 37 which is adapted to receive a plurality fillers 38 of various thickness of predetermined relative calibrations. Resting on top ot the uppermost I'iiling element is tree coilar which tits within the cup 37 and is l' provided with a iiange L10 by whch the free l tive to th cellar 39 may be readily raised out ot the cup 37, where-hy liilers of predetermined combinations may be placed in the base ot the cup 37 to late the relation of the rod 17 relae sieeve 19, whereby the extent of closing ot the jaws 1 2 and 8*#1 may be minutely controlled.

Thus it will be seen that the coacting cam surfaces 2O and 21 function to provide coarse adjustment of the rod 17, relative to the sleeve19, to operatively connect the jaw controliing rod 17 with the actuating sleeve 19 tor actuation of the jaws .1-2 and 3 4, and to disconnect the rod 17 'from the actuating sleeve 19, while the iillsrs provide for delicate adjustment between the rod 17 and sleeve 19 for minutely controlling the ciosing of the jaws and the pressure exerted by the jaws on the stocking gripped between the jaws, and the iatch 231 serves as common means tor maintaining both the coarse and i'ine adjustments of the jaw-controlling rod 17 relative to the jaw-actuating sleeve 19.
